How To Inspect The Quality of Extruded Polyethylene Foam Board

Views: 115     Author: Site Editor     Publish Time: 2024-02-29      Origin: Site

The extruded polyethylene foam board has high compressive strength, equally low thermal conductivity and long-lasting thermal insulation performance. XPS extruded board is a kind of thermal insulation board with polystyrene and foaming agent as main raw materials, which is formed by high temperature mixing and extrusion, with continuous uniform surface layer and closed-cell honeycomb structure. There will be no gaps in the plates of these honeycomb structures.



Before installing, how to check the quality extruded polyethylene foam board material?


Polyethylene Foam Board


Visual Inspection of Polyethylene Foam Board


Check if the surface of the XPS board is smooth, free of cracks, bubbles, or depressions, and if the colour is uniform. Visual inspection can preliminarily assess the manufacturing quality and surface flatness of the XPS board.


Dimensional Inspection of Polyethylene Foam Board


The dimensions of the XPS board should meet design requirements and production standards, including length, width, thickness, etc. Measuring these dimensions helps verify the accuracy and consistency of the XPS board.


Density Check of Polyethylene Foam Board


Density is an important indicator of XPS board quality. It can be measured using a density meter or by weighing. Generally, higher density indicates better insulation performance and strength of the XPS board.


Mechanical Performance Check of Polyethylene Foam Board


This includes compressive strength, flexural strength, etc. These performance indicators can be evaluated through laboratory tests to ensure that the XPS board has sufficient load-bearing capacity and durability.


Combustion Performance Check of Polyethylene Foam Board


The combustion performance of XPS board is crucial for its safety in buildings. Common test items include combustion performance rating, smoke generation, flame spread, etc.


Water Absorption Check of Polyethylene Foam Board


The water absorption of XPS board affects its insulation performance and service life. The water absorption rate of XPS board can be tested using methods such as immersion or weighing after drying.


Environmental Protection Check of Polyethylene Foam Board


Ensure that the XPS board complies with environmental standards, such as whether it contains harmful substances or meets relevant national environmental regulations.

These are common methods and indicators for quality inspection of XPS board. Depending on the specific circumstances, appropriate testing methods can be chosen to ensure that the quality of the XPS board meets the requirements. Additionally, it is recommended to engage reputable testing organisations with relevant qualifications and credibility before using XPS boards.


How to check the quality of the installed extruded polyethylene foam?


1. The specifications and technical specifications of extruded board and grid cloth, and the quality of raw materials for polymer mortar must meet the requirements.

2. The extruded board must be firmly glued to the wall, without loosening and virtual stickiness.

3. Polymer mortar and extruded board should be pasted closely, without delamination, hollow drum, surface layer without explosive ash and cracks.

4. The total sticking area between each extruded board and the base surface is 30-50%.

5. The bulging part of the fixture entering the structural wall is not less than 50.

6. No adhesive is applied to the butt seam of the extruded board.

7. The grid cloth should be horizontally laid, pressed and dense, and there can be no empty drums, wrinkles, warping edges, exposure, etc. The lap width is not less than 100 in the horizontal direction and 80 in the vertical direction.

8. The thickness of polymer mortar should not be greater than 4, and the thickness of the first layer of the building should not be more than 5.
